You do two experiments. In the first experiment you have two groups of 25 people (i.e. 50 people in total), use a t test for independent groups, set alpha = .05 one tailed and calculate beta to be .15. In the second experiment you have 200 people, do a t test for correlated groups, set alpha = .01 two tailed and calculate beta to be .25. Which experiment is more powerful? (i.e. the power is higher) a) the first b) the second c) both are t tests, so they are equal d) it is impossible to tell from this information

Question 1 A.) Check whether the following signals are periodic and determine the fundamental period. i.) $x_1(t) = cos^3(t)$ ii.) $x_2(t) = sin(t) + cos(\pi t)$ iii.) $x_3[n] = \sum_{k=-\infty}^{\infty} (\delta[n - k] + \delta[n - 2k])$ iv.) $x_4[n] = cos(0.7n)$ B.) Use clear and detailed mathematical steps to check the linearity, causality, stability and time-invariance of the following system $y(t) = x(t)x(t+5) + 3x(t-2) + 12$
